This section explains how medical assistance units (MAUs) are constructed for programs not based on modified adjusted gross income (MAGI) methodologies. (MAGI-based programs are described in WAC 182-503-0510.)

(1) An MAU is a person or group of people who must be included together when determining eligibility. MAUs are established based on each person's relationship to other family members and the person's financial responsibility for the other family members. MAUs for non-MAGI-based programs include an applicant and persons financially responsible for the applicant as described in subsection (2) of this section (as limited by subsection (3) of this section).

(2) Financial responsibility applies only to spouses and to parents, as follows:

(a) Married persons, living together are financially responsible for each other;

(b) Natural, adoptive, or step-parents are financially responsible for their unmarried, minor children living in the same household;

(c) Minor children are not financially responsible for their parents or for their siblings;

(d) Married persons' financial responsibility for each other when not living together because one or both are residing in a medical institution is described in chapter 182-513 WAC.

(3) The number of persons in the MAU is increased by one for each verified unborn child for each pregnant woman already included in the MAU under this section.

(4) A separate SSI-related MAU is required for:

(a) SSI recipients;

(b) SSI-related persons;

(c) Institutionalized persons;

(d) The purpose of applying medical income standards for an:

(i) SSI-related applicant whose spouse is not relatable to SSI or is not applying for SSI-related medical; and

(ii) Ineligible spouse of an SSI recipient.

(5) When determining eligibility for an SSI-related medical program, the agency determines how household income is allocated and deemed to the SSI-related person according to the rules described in WAC 182-512-0820 and 182-512-0900 through 182-512-0960.
